Thanks Chrismp but I did follow thier build and I'm still having leaks. I am going to try folding each end of the hose back on itself and then bolting it all down. As for the valve leaks, I decided to try an automotive gasket to make it airtight. I am inflating tomorrow to check again.

So I just built a pneumatic press and have been trying to stop leaks for the past week before I actually press a board in it. I am dealing with leaks at both ends of the tube and at the valves. What order do you have your valve set up in Falls?
